“I want to keep writing — but maybe about something else. I’m going to keep doing it until the holidays.”

Her father David, 39, a smallholder, said she was quitting because she wanted to try something new.

This will not be the end of the NeverSeconds blog.

Mr Payne plans to invite school classes around the world to take it over and write about their meals for a week each, and has already attracted interest from New Zealand.

In an exclusive interview in tomorrow's Daily Telegraph, Martha also reveals what it's like to be at the centre of the media storm that has surrounded her school meals blog.

She has received Hollywood offers, invites to film premieres and appeared on international news.

"It's really annoying because everybody wants to talk to me," she told the Telegraph.

“I thought my friends and family would read it but now it’s people all over the world."

The nine-year-old schoolgirl spoke about how her classmates feel about her blog, as well as how "shocking" it was when Argyll and Bute council officials banned her from taking photographs in the school canteen.

Martha, whose father Dave helps her with the blog, told the Telegraph she was upset because she started the blog as a writing project and didn't want to stop halfway through.

"We've never wanted to campaign," her father explained.

Meanwhile the blog raised nearly £100,000 for the charity Mary's Meals, which helps feed children in east Africa.
